With a combined 380 hp, the Porsche Panamera S Hybrid impressed us with its spry handling, ample power, and ultra-luxurious interior. But with an as-tested price of $110,680, would it be your pick? Or would you choose the GS Hybrid, with its combined 338 hp, 29/34 mpg city/highway fuel economy, and slightly easier-to-swallow MSRP of closer to $70,000? The Inifiniti M35h has a combined output of 360 hp and is relative value at $65,395; would its curvy sheetmetal persuade you to get into its driver's seat?Tell us which of the three hybrid luxury sedans you’d choose in the comments section below and don't miss the comparison test here.

i would take that infiniti cause of the interior and i would rob another infinti M37S and switch the wheels plus that infiniti has more torque than both lexus & porsche and might be a couple pounds lighter thats why its the quickest

This coming from someone who spelt both dimwit and shit wrong. The fact is killdetroit, you're mad because you can't afford the XTS, LaCrosse or any of the German cars that you praise. What a buttsore baby.
Tina, yes there is a subtle difference, but if I'm looking for a luxury car then FWD will get better MPGs and it will handle inclement weather better. My Boxster is what I want to be RWD because you can actually use it.

what german quality? Toyota and Nissan are constantly at the top of quality surveys.Besides how much are you really paying for the porsche over the years of ownership.Why should toyota the leader in hybrid technology and nissan with the leaf be worried about an overly expensive hybrid formula.

As a Lexus aficionado I actually have to agree with mt411 sentiment in regards to the cramped front interior space of the new GS! I do feel that the 2013 GS is best sports sedan on the market currently, but in this segment of vehicles the German competitors beat Lexus in overall interior ergonomics.
I'm 5'11 and personally I think the interior is a little too snug and confining, and I don't why Lexus even bothered adding door armrests as they are basically nonexistent on the GS.
But IMO if you can actually fit inside and get comfortable/cozy (the seats are excellent by the way) the Lexus GS clearly the best choice!

What does FWD have to do with this? Can you honestly give me an example when you have driven a large RWD sedan and the fact that it was RWD made a difference? Honestly I disagree with LeTroll, but the XTS is preferable to any of these in my opinion. The Panamera is just a badge on an ugly hump of metal.

Porsche. It is a true Porsche. It isn't made to some one else's standard, but to Stutgart's own. It is very well made and engineered. Quality above Nissan and Toyota. Usable ergonomics. It is the performer of the bunch, outside of 0-60 times. I like the other two, but walking out to my parking space, would rather see the Porsche sitting there and would rather have the performance on the drive home after a long day at work. The Japanese should be very worried that Germany is tackling the Hybrid formula so succesfully.

Preference is in the eye of the beholder. If you are looking for the most for you buck, Infiniti, better warranty and cost, while still being fast. If you have some extra cash, want something looks like an IS and just as fast as the rest of the three, but just bigger, go with Lexus. But, if you have wealth and want to do something about the eviroment at the same time, go with the Porsche . The truth of the matter is that, they will all go around the same speeds when you are traveling to work at 8am... But what I find really interesting, is that at the end of the day most of the buyers, of these cars rarely keep them more than 4 -5 years, to whom they may matter the most is those buying them off lease, I wonder how these cars will hold up then, performance and cost wise.....

The base V6 Mustang is on the same platform as the M3-beating Boss 302 as well. It all depends on the major components, like engine and transmission tuning and output, suspension, chassis strengthening, etc. I highly doubt the hybrid version feels anything like the 'sporty' version.

Paying all that cash for a Porsche is no longer the smart thing to do no matter how sexy the car and the name might be and not to mention when the competition has caught up to them. The Lexus? Nah! Although it looks good I just don't like it. I would choose the Infiniti. Better overall choice.

Did you see the test with the GS F-Sport ?
" am an enthusiast and the Lexus is not designed for those of us who like to drive"
umm yea in a recent test the Infiniti M Sport took dead least . . . . While the GS F-Sport took first even ahead of the BMW 5.
You were saying ?

If you want Fun to drive the Lexus GS F-Sport will wipe the floor with the infiniti the Infiniti just took last place in the test with the Lexus.. so saying the infiniti is more " fun " is incorrect.... Lexus has performance and technology.

What does the amount of vehicles sold matter? These are there also for CAFE purposes. CAFE just asks for a standard average FE across the line, and doesn't care how many are actually sold. Porsche can just have them for sale in the showroom and sell none and still have CAFE happy simply because the average is up.

I tried out every Lexus on the lot. Other than the 450h, my head rubbed up on the roof liner of every single one. Lexus ergonomics are horrible for a tall person - lean the seat back far enough to get your head off the roof and the steering wheel is too far away - not enough telescope. Move your seat in and your knees are on the console or the steering wheel.
The Porsche is just ridiculously expensive for what you get.
The Infiniti has that weird protuberance on the dash. Lesser of all evils? The Infiniti M35h.

I'd have to go with the Infiniti M. I think, unlike Motortrend, it provides the perfect blend of sporty handling, straight line performance (Is faster or keeps up with the Porsche in all speed ranges), luxurious interior and possibly the lowest price. I would be more than glad to have a car that can do 0-60 in 5.1 secs and still pull 30+ mpg. I think Nissan/Infiniti did a GREAT job with their hybrid system to say this was their first shot at it. Seems they could easily de-tune it and get the same MPG numbers as the GS. Thats one helluva way to come out the gate and pretty much be on par with the leader of hybrids. Its obvious Infiniti wants to market their hybrid focused both on economy and performance so there is a small sacrifice in MPGs, but not much.
But the GS is a close second. The car simply deserves its respect. Lexus too for completely switching it up.

sorry, i've driven the lexus many times and it's a plasticky piece of crap compared to the porsche. yeah it's got a good powertrain but interior materials are not luxury car quality... nice toyota maybe but not on par with a german luxury car let alone a porsche

Well obviously if the keys were being dangled in front of me, I'd take the Porsche. But for the purposes of this test, and when it comes to buying one, I admit it'd be the Lexus. It seems to have the best hybrid tech, is reasonably priced, drives well, and I love its styling, inside and out. And the money I saved by not buying the Panamera would put a really nice 993 in the garage next to the Lexus.

For me it's a draw between the Lexus and the Infinity. The Porsche is over priced and who wouldn't want a real Porsche or M5 for that price. Both the Lexus and Infiniti are attractive, cheaper and have good quality. But the scale tips to the Lexus because, lets face it, Toyota is the Hybrid expert. But then again the Infiniti has the fun to drive characteristic.
But I have to go with the Lexus. It has the best technology and now that I think about it, it's the most attractive from the group, IMO. Or I can just wait for the ActiveHybrid 5.

you sir, are a god among men. If you are going to spend that kind of cash, you can afford the gas. Why not have fun, utility, and enough grunt and pure enthusiast bliss? I would love to go to Lowe's, load the trunk, my wife, and the kid and still dust mustangs and camaros all day long.

These brands are about showing money and power. But they also have a reputation of "gas guzzling sports cars/sedans." So what better way to show off you're rich AND environmentally friendly? Does it matter that many a normal (and still quick) V6 powered vehicles can match them? No. It's a hybrid, and that's all the difference in the world of perception and snobbery. That doesn't make any of these efforts any less good or bad. The fact we can opt for speed, luxury, and less carbon out the tailpipe are all nice options for those who may be interested.
